5
Step-by-step explanation:
Take the number of markers and divide by the number in each package
70/15
4.6666repeating
Round to the nearest whole number to determine the number of packages
5
They will need to buy 5 packages
We can Notice that ∠ABC = ∠ACB
We know that if Two Angles are Equal then Angles Corresponding to those Sides are also Equal.
⇒ AB = AC
⇒ 4x + 4 = 6x - 14
⇒ 6x - 4x = 4 + 14
⇒ 2x = 18
⇒ x = 9
⇒ Length of BC = 2x + 7 = 2(9) + 7 = 18 + 7 = 25 units
About 1.19 %
80*1.19= 95.2 Since 2 is not 5 or above it get knocks down to 95 exactly
